The Archaea domain was the last major category to be added to the system of classification in the 1970s, recognizing a distinct group of single-celled microorganisms with unique genetic and biochemical properties.
The highest, most inclusive category is typically the domain or overarching theme that encompasses all other categories within a classification system.
It is Domain.
The classification system in biology is a system which helps scientists organize or name different things and types of objects and organisms. Taxonomy is the classification system for grouping and naming living things under their main domain category (see related questions about the Domain category of classification).The classification system of taxonomy must be done in a certain order following the Domain:KingdomPhylumClassOrderFamilyGenusSpeciesAn example using the domesticated dog classification is:Kingdom Animalia Phylum ChordataClass MammaliaOrder CarnivoraFamily CanidaeGenus CanisSpecies/subspecies C. lupus familiarisA mnemonic device (acronym) to help you learn and memorize this order is:KingPhilipCameOverForGrapeSodaORKingPhillipCameOverForGoodSoup
The first and largest category in the classification system is the domain, which represents the highest level of biological organization. The three main domains are Bacteria, Archaea, and Eukarya.
The largest classification in the biological hierarchy is the domain. There are three domains: Bacteria, Archaea, and Eukarya. Eukarya includes organisms such as plants, animals, fungi, and protists.
The first and largest category in the classification system is a kingdom.
The largest taxonomic category in Linnaeus's system of classification is the kingdom.
The least specific taxonomic classification is Domain. It represents the broadest level of classification in the biological classification system.
